A drywall sub in Pembroke Pines sends a certificate to the general contractor on Monday. Wednesday it comes back rejected. The compliance desk flagged three lines: no completed operations additional insured, no waiver of subrogation on the workers' compensation policy, and a primary and non-contributory box checked with nothing behind it. The crew is scheduled for the following week and cannot set foot on the site until it is fixed.
None of that is a paperwork technicality. Each line names a specific endorsement that has to be attached to a policy, and two of them carry a price. Here is what a Florida construction contract is actually asking for, what compliance costs, and where Florida law quietly rewrites the indemnity clause the whole arrangement hangs on.
A Certificate of Insurance Proves Almost Nothing
The form you send is an ACORD 25, Certificate of Liability Insurance. Read the header block on your own copy. It states that the certificate is issued as a matter of information only and confers no rights upon the certificate holder, and that it does not affirmatively or negatively amend, extend or alter the coverage afforded by the policies listed.
That sentence is doing heavy lifting. The certificate is a snapshot of what sat on the policy the day an agent printed it. It is not a contract, the certificate holder is not a party to your policy, and checking a box on it adds no coverage whatsoever. If the general contractor wants rights under your policy, the policy itself has to be endorsed.
The ACORD 25 has checkboxes for additional insured and subrogation waiver. A checked box only records that somebody asked. The endorsement attached to the policy is the only document a claims adjuster will read three years later when a completed operations suit lands.
This is why sophisticated general contractors in Broward and Miami-Dade now ask for endorsement copies rather than the certificate alone. Send the actual endorsement pages along with the COI and most rejections disappear before they happen.
Additional Insured: Two Forms, Two Halves of the Timeline
Naming someone as an additional insured extends your liability policy to cover them for claims arising out of your work. The general contractor gets defense and indemnity under your policy instead of burning their own limits and their own loss history. That is the whole point of the request: your crew caused it, so your policy should answer for it.
The forms most Florida construction contracts ask for split along the project timeline.
| Endorsement | What it does | When it matters |
|---|---|---|
| CG 20 10 (04 13 edition) | Additional insured for your ongoing operations | While the crew is still on site |
| CG 20 37 | Additional insured for your completed operations | After the job is signed off, often years later |
| CG 20 01 | Primary and non-contributory other-insurance condition | Keeps the GC's carrier from sharing the loss with yours |
CG 20 10 stops when your work stops. Ongoing operations does not include completed operations, so if a balcony rail your crew installed in 2024 gives way in 2027, the CG 20 10 is long spent and only the completed operations form responds. Florida construction defect claims routinely surface years after the certificate of occupancy, which makes CG 20 37 the endorsement that matters most and the one subs most often skip.
Primary and non-contributory is the third piece. Without CG 20 01, both policies are arguably primary, and the two carriers spend months arguing over shares while the defense bill runs. With it, your policy pays first and does not ask the GC's carrier to contribute.
Most carriers will write a blanket additional insured endorsement that automatically picks up anyone you are required by written contract to name. Blanket forms are cheaper and faster than scheduling each certificate holder individually, and they usually satisfy compliance software. Read the trigger language before you rely on one: some blanket forms only apply where the written contract was executed before the loss occurred.
Waiver of Subrogation Is You Giving Up a Right to Recover
Subrogation is the right your insurer has to pay your claim and then pursue whoever actually caused it. A waiver of subrogation closes that door for a named party. If the general contractor damages your equipment, or a site condition the GC controlled injures your employee, your carrier pays the claim and gives up the right to go collect from the GC.
Two different waivers show up in a construction contract, sitting on two different policies:
- General liability: ISO form CG 24 04, Waiver of Transfer of Rights of Recovery Against Others to Us. Commonly added at no charge or for a small flat fee.
- Workers' compensation: NCCI form WC 00 03 13, Waiver of Our Right to Recover From Others. This one costs real money. Carriers typically charge a surcharge in the range of 5 to 10 percent of the manual premium developed for that job, sometimes more, and a blanket waiver covering every contract costs more than a scheduled waiver naming one GC.
- Commercial auto and commercial property: waivers are available on both, and equipment-heavy trades are increasingly asked for them on hauling and rigging work.
The workers' compensation waiver deserves a second look because of how Florida handles third-party recovery. Under Florida Statute 440.39, when an employee is injured by a third party, the comp carrier that paid benefits holds a statutory lien and can recover against that third party. Signing a waiver for the general contractor means your carrier forfeits that recovery. Carriers price the endorsement because they know precisely what they are giving up.
Florida Law Rewrites the Indemnity Clause These Endorsements Back Up
Additional insured status and the indemnity clause in the contract are two separate promises, and Florida regulates the second one. Florida Statute 725.06 governs indemnification in agreements for the construction, alteration, repair or demolition of a building, structure, appurtenance or appliance, between an owner and architects, engineers, general contractors, subcontractors, sub-subcontractors or materialmen.
The core requirement: an indemnification provision is unenforceable unless the contract contains a monetary limitation on the extent of the indemnification that bears a reasonable commercial relationship to the contract and is part of the project specifications or bid documents. Where the indemnitee is the owner of the real property and the indemnitor is in privity of contract with that owner, the statute sets a floor. The limitation may not be less than $1 million per occurrence unless the parties agree otherwise.
Public work is narrower still. Under subsections (2) and (3), a contract with a state agency, county, municipality or other public agency may require indemnification only to the extent caused by the negligence, recklessness or intentional wrongful misconduct of the indemnifying party. Anything broader is void as against public policy. If you bid municipal work in Broward County, the hold-harmless language you signed on a private job does not carry over.
A contract handed to you with an unlimited hold-harmless clause and no dollar cap may well be unenforceable under 725.06. That is a question for a construction attorney, not an insurance agent, but it is worth raising before you sign. Your insurance obligations survive either way, so get the endorsements regardless of how the indemnity argument turns out.
Keep the two obligations separate in your head. Even where 725.06 trims the indemnity clause, the contract's insurance article still binds you to carry the limits it names and attach the endorsements it lists.
What Compliance Actually Costs a Florida Sub
Price these before you bid, not after the certificate bounces. Figures below are the ranges we see on South Florida contractor accounts; your own carrier, class code and loss history move them.
| Requirement | Typical Florida cost |
|---|---|
| Blanket additional insured, ongoing plus completed operations | Often built into the base rate, otherwise a few hundred dollars on the GL premium |
| Scheduled additional insured, per certificate holder | Commonly $50 to $150 each |
| GL waiver of subrogation (CG 24 04) | Frequently included, sometimes a small flat charge |
| Workers' comp waiver (WC 00 03 13) | Roughly 5 to 10 percent of the manual premium for that job |
| Going from $1M/$2M to $2M/$4M general liability | A commercial umbrella over the existing GL is usually cheaper than rewriting it |
That last line matters more than most subs realize. A general contractor asking for $2 million per occurrence rarely cares whether the limit comes from a larger general liability policy or from a $1 million GL sitting under a $1 million commercial umbrella. The umbrella route is normally cheaper, and a follow-form umbrella carries the additional insured and waiver language up from the underlying policy. Confirm it follows form rather than assuming it does; some umbrellas carve out additional insured status.
The Five-Minute Contract Review Before You Sign
Pull the insurance article out of the contract and work the list. Most Fort Lauderdale and Miami general contractors use variations of the same template, so once you have done this for one job it takes minutes on the next.
- Find the required limits, per occurrence and aggregate, and check them against your declarations page rather than against memory.
- Note whether completed operations additional insured status is required. If the contract says ongoing and completed operations, you need CG 20 10 and CG 20 37 both.
- Look for primary and non-contributory language. That is CG 20 01, and it has to be on the policy, not noted on the certificate.
- Find the waiver of subrogation requirement and read which policies it reaches. General liability only is cheap. Workers' compensation is the one with the surcharge.
- Check the notice of cancellation requirement. Many contracts ask for 30 days' notice to the certificate holder, which needs its own endorsement; no carrier will provide it through a certificate notation.
- Check whether you must name the owner and the construction lender as additional insureds, not just the GC. Multi-party requirements on a Fort Lauderdale mixed-use job are routine.
- Send the entire insurance article to your agent rather than a summary. Paraphrasing is how a missing completed operations endorsement gets discovered eighteen months later.
Florida contractors also have to clear the workers' compensation threshold before any of this matters. Construction is the strict category: coverage is required from the first employee under Florida Statute 440.02 and 440.10, while non-construction employers can run up to four. Corporate officers in construction may elect an exemption, but no more than three officers across a corporation or group of affiliated corporations, and the election carries a $50 application fee. A GC's compliance system checks exemption status against the state database, and an expired exemption reads exactly like no coverage at all.
Miami Premier Insurance writes general liability, workers' compensation, commercial auto and commercial umbrella for Broward and Miami-Dade trades, and our commercial insurance page lists what a contractor account normally carries. Certificates and endorsement copies go out the same day on active accounts.
The endorsements are cheap next to the job they unlock. A rejected certificate costs you a start date. A missing completed operations endorsement can cost you a defense you assumed somebody else was paying for. Get them onto the policy before you need them, and keep a current copy of every endorsement in the same folder as the certificate.
